Background: Recent data describe that the gonads of patients with partial gonadal dysgenesis (PGD) and mutation in the NR5A1 gene can present with a different histological pattern.Objective and hypotheses: To evaluate histological aspects of PGD caused by NR5A1 mutations.Method: Five patients with PGD, a history of gonadal biopsy or gonadectomy and confirmed mutation on NR5A1 gene were selected from a Bra...

Background: Severe deficiency of 11β-hydroxysteroid dehydrogenase type 2 (11βHSD2) triggers activation of mineralocorticoid receptor (MR) by cortisol and causing apparent mineralocorticoid excess (AME) syndrome characterized mostly by low-renin arterial hypertension and hypokalemia. In 2003, we studied a patient with AME (3 years-old) having two homozygous mutation, D223N (rs121917833) and a SNP C>T in intron 3 (rs376023420) (Carvajal et al. JCEM 2003).<p cla...

Background: X-linked hypophosphatemic rickets (XLH) is caused by inactivating mutations in the phosphate-regulating gene with homologies to endopeptidases on the X chromosome (PHEX). In this group of patients, data about renal calcifying disorders are scarce.Objective and hypotheses: To determine the prevalence of nephrocalcinosis and nephrolithiasis and their risk factors in XLH patients.Method: 36 patients (15 children a...

Background: Elevated blood pressure (BP) may occur from childhood, increasing the risk for hypertension in adulthood.Aim: To investigate the effect of anthropometric characteristics and lifestyle habits in children’s and adolescents’ BP.Methods: 949 children (<12 years old) from Lakonia, 178 teenagers (12–18 years old) from Athens and 372 from Kalamata, Greece, had participated during 2011–2014. A specially ...

Background: Some IGFALS variants have been reported in more than one ALS-deficient family raising the question whether they originated from a single common ancestor allele (founder effect) or alternatively, as independent mutational events (hot spot). Since c.103dupG (p.E35Gfs*17) is located in a stretch of five consecutive guanine residues, where both G-duplication and deletion have been described in several families, we speculate that this region could be a hot spot...

Background: Hypogonadotropic hypogonadism (HH) in females is an uncommon and heterogeneous condition. There is little data regarding biochemical profile of gonadotropins to further substantiate the diagnosis.Objective: To evaluate the gonadotropaic secretion profile after GnRH infusion in a female cohort diagnosed with HH.Patients and methods: GnRH iv infusion test (0–120 min) were performed in 17 patients (17.5±2.3 years...

Background: Familial hyperaldosteronism type 1 (FH-1), is caused by the presence of a chimeric CYP11B1/CYP11B2 gene that produces high amounts of aldosterone in response to ACTH and severe hypertension. An early diagnosis and treatment are important, not only to manage hypertension but also to avoid possible deleterious effects of aldosterone on the endothelium and cardiovascular diseases.Clinical case: A 3 months old boy was referred for evalua...

Background: Uric acid and Triglycerides/HDL ratio are an important risk factor for cardiovascular diseases.Aim: To investigate how Triglycerides/HDL ratio and uric acid are correlated with children’s biochemical and anthropometric characteristics, depending on the predisposition for metabolic syndrome (MetSyn).Methods: 110 students, 6–12 years old, living in Sparta-Greece, participated in our research. Anthropometric and ...

Background: Sleep is a complex and essential biological process that is required on a daily basis for all humans, playing a vital role in the maintenance of the homeostasis in short and long term.Aims and objectives: To investigate the role of sleep hours in correlation with risk factors for metabolic disorders in a children population.Methods: The program was implemented in 949 children (5–12 years old) living in Sparta-Greec...

Background: Childhood obesity is considered to be an epidemic in developed countries that can negatively affect children’s health and psychology.Aims and objectives: To investigate the nutritional and environmental factors that lead to the presence of childhood obesity and its complications.Methods: A total of 949 students, 3–12 years old, living in Sparta–Greece, have participated in our research. Their lifestyle an...
